The EC90 Zero is the lightest seatpost in the Easton line, thanks to its full carbon fiber construction (including the upper and lower clamping plates). This thing is plenty strong too. By incorporating RAD (Relief-Area Design) and TaperWall technology, the EC90 Zero has been intelligently designed to distribute stress along the length of the post. Easton also removes material in critical clamp zones to prevent pinching the carbon (which can sacrifice durability).
